Horizon Worlds Link to Unity Game

How can I make a link from within a Meta Horizon World to a Meta-approved Unity-based game without the "quit app?" message being displayed?

My Horizon World will be a meeting place for experiential time travel adventurers.

All that's required is a Meta Quest and a wi-fi connection.

I plan to build a feature in my simulation game thusly--

If the realism gets too intense, a player can RETURN to the 'friendly' Horizon Worlds launch spot at any time.

I would like to coordinate development with Meta similar to what Universal Studios has done in Horizon Worlds.
